i NEED to wire in a Kill switch. i dont want anything fancy, a simple toggle will do ok. but i am not sure which wire to interrupt. i am tempted to interrupt the accelerator since itz just a fake joystick anyway, not a real gas pedal. but the darn thing is so voltage sensitive that i think i would mess it up. so what wire is easy and safe ???
Wire up the switch to the ECU relay that is to be removed "in case of an emergency." This official "firs responder" information should help. https://techinfo.toyota.com/techInfoPortal/staticcontent/en/techinfo/html/prelogin/docs/1stprius.pdf
You're very welcome. Just find the wire going to the relay that switches it and place the switch in between. It should be easy.
